I agree that the whole line of thinking that he's of satan is a bit over the top. David Blaine has done nothing that David Copperfield hasn't done (a few years back...or Houdini...a few more years back). It's all illusions and taught through over priced videos for sale all over the internet. He does card tricks, coin tricks...yeah, that levitation thing is pretty crazy, but it's not of the devil. And he's made it quite well known that all of his tricks are nothing but that...TRICKS. He's been practicing since he was a child (he's in his 30's now, I believe) and these are the fruits of his hard work.
As far as that ice trick, well, come on, how is that much different than people who push the limits of survival in other ways...climbing Mt. Everest, or HALO skydiving, or whatever. People go to all sorts of extremes (and are quite public about it) but that doesn't make it evil.
I find it really cool to watch and also I've always been impressed with the fact that he's not charging outrageous amounts of money for people to come and see his show. In fact, it seems that he goes out of his way to entertain the homeless, or those in poor communities, or street kids with no real goals in life. Don't get me wrong, I know he's got millions, but I think his brand of 'street magic' is a lot more commendable than some Las Vegas performers who charge $60 a seat to sell out a show.
Anyway, sorry I went off into a bit of a rant, but I just find the idea that he's involved in some kind of evil brand of magic way out there.
Love, Heather
